Struct PatternEffectiveness 

pub struct PatternEffectiveness {
    pub times_retrieved: usize,
    pub times_applied: usize,
    pub success_when_applied: usize,
    pub failure_when_applied: usize,
    pub avg_reward_delta: f32,
    pub last_used: DateTime<Utc>,
    pub created_at: DateTime<Utc>,
}

Tracks the real-world effectiveness of a pattern based on actual usage

Fields

times_retrieved: usize

Number of times this pattern was retrieved in queries

times_applied: usize

Number of times this pattern was explicitly applied

success_when_applied: usize

Number of successful outcomes when applied

failure_when_applied: usize

Number of failed outcomes when applied

avg_reward_delta: f32

Average reward improvement when this pattern was used (can be negative)

last_used: DateTime<Utc>

When this pattern was last used

created_at: DateTime<Utc>

When this pattern was created

Implementations

impl PatternEffectiveness

pub fn new() -> Self

Create a new effectiveness tracker

pub fn application_success_rate(&self) -> f32

Calculate the success rate when applied (0.0 to 1.0)

pub fn usage_rate(&self) -> f32

Calculate the usage rate (applied / retrieved)

pub fn effectiveness_score(&self) -> f32

Calculate an overall effectiveness score (0.0 to 1.0+) Combines success rate, usage rate, and reward delta

pub fn record_retrieval(&mut self)

Record that this pattern was retrieved

pub fn record_application(&mut self, success: bool, reward_delta: f32)

Record that this pattern was applied with an outcome

Trait Implementations

impl Clone for PatternEffectiveness

fn clone(&self) -> PatternEffectiveness

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PatternEffectiveness

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PatternEffectiveness

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PatternEffectiveness

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PatternEffectiveness

fn eq(&self, other: &PatternEffectiveness) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PatternEffectiveness

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
